About this product

The Black Rain Ordnance Fallout10-SI is a modern sporting rifle built around .308 Win (7.62×51) chambers and an 18-inch 4150 chrome-moly barrel. It uses billet 7075-T6 aluminum upper and lower receivers with a hardcoat anodized finish and a Luth-AR MBA-1 stock paired with a GI-style grip.
